The building shown in Fig. 1 has seven ioor levele which have floors formed in the shape of slash?. ihren slabs are formed oi ri-iinloroed eimerete in such manner that no floor benne :ire enniiloyed, The Hoor Siebe :ire ennnorieil e number of round posts l suitiiblj; ned on the interior of the building. e r poele 2 along the edges of the timore heel; oi the :web 3 which form a pmt or lill of tl i enter nrfuee of the buildingl :iloiigg the in the Structure shown in Figi?. l i, siitnble piers, Snell :is shown ui. fi. :ind i3, milj' be employed to eohfn'iee the beauty of the building, While eerxing in i :eine time the function of supple-ll tot leed of that portion oi the floor.

Thom 'piers and Corner posts reet upon the foundation of the building.

The outer eligen of the floors ere snpY ported luiteren the poete *E :incl the piers Al, 5, .f3 :unl T by means of the spendi-els S nhieh :ire formed integral therewith. As shown in lfig's. il, i' und S. the fiom' inembor l0 'hir-li is formed as; a rein'toi'eed oonerete Shri; provided with the deprvsseil panel il :above the engi i2 ot' the column portion i3 whieh iippmts the pertienlr seetirni or floor. lli if; to be limit-.intend that suitable forme nre eoi'ieirneted into which the cont-rete poured so that these parte are formed sub ntially et one operation. The spendi-el reii'il'oreed in the manner indicated in fr The emmdre and the eolilniifan ii if lie und? umn are tied together by suitable diagonal reinforcing rode` Q5 which join tbe column and the spandrol together. These rods 25 eonnee with the reinforcing members 26 nliieh ere embedded in they body of the evendi-el 8. The body of the column portion i3 is reinforced by diagonal rods Z7 which pese diagonally through the column een ,l2 sind connect with the Hoor slab 10. The eoluinn portion H projeete intothe side of' the spandrel for a short distance 1n order to secure room for reinforcement between the epiinilrel and the portion 1l of the column. The top face of the spendrel is provided with e. projecting ridge 15 which terms u sill. This; sill ie undercut es shown in Figs. (i :ind 7 to deiino a drip edge which prevents rain, moisture and the like from def-.icing the outer face of the spandrel 8. The sinh il is placed substantially on the renter line of the speudrel 8 and is thus epiieed :muy from the columns so as to permit light and air to pass therebetween.

il cnn be seen that the edges of the floors :are .Supported from behind the sash instead of beingr supgoried by posts or pihisters in line with the 'Sash an forming an exterior Surface of the building es hee previously been the practice. The edges 1n front of the rohmine are thus free. of any SupportL ing poets in, front of the columns. f

in Fig'. 10 I have Shown a. construction wherein the spandrel 8 is spaced away from the eohunri portion 14 to leave a clear space il'ierebeween. This arrangement provides Vfor more room between the sash and the f-oluum. 1n Fig. 11 I have shown the spandrel are connected to the column portion 14 h v e filling 17 which permits of reinforcing rode being passed from the epzindrel to the Column. brarkot or console 18 may be employed to connect the spandrel with the column portion 13.

Fig. l shows a similar arrangement exeopt that the fillingr portion 17 as Well as the brueket or console portion 18 are made o the width of the column. In the construction shown in Fig. 13 I have dispensed with the spandrels. In this form ot' con` etruetion the sil-Sh 3 is carried on past the 'floor so as; to present a continuous front of glues. The sush 3 is supported at the floor by ineens of a suitable support 21 such as :in angle iron or the like, that is fastened by inserte into the body of the concrete floor member 10. Y

Tt apparent that the greater the pereentngiof transparent material, that is sash. employed, the less resistance will there be to the passage of lightto the interior of the building. Placing of the supporting rohunn bueh o1"- the line of sash provides a structure which possesses sufficient strength to Ineke possible the additional inflow of lightt without saericin to any material extent the efficient flieposition of the mate laterally, and lines of sash exienf'linn be tween Said piers and joining saisi sjmi'nli'els, said sash lying in a plane in iront of 'mid columns and being;r continuons post @nid columns.
